Lindsay Clancy's family was "very concerned" about her mental health in the months before she killed her three kids, according to court testimony.

Lindsay Clancy, 36, is charged with three counts of first-degree murder in the deaths of her three children — Cora, Dawson and Callan, all under 6 years old, who were found strangled in the family's Duxbury home in 2023.

Prosecutors concluded their case Monday morning.

The jury seated to hear the case consists of 12 women and six men, though six of those people are alternates.

During the trial on Tuesday, Susan Clancy, Lindsay's mother-in-law, told jurors she was concerned about her mental health during the holiday season in 2022, but said she was a caring mother.
